The tibial nerve is an offshoot of the sciatic nerve at the back of the leg which travels down the leg and eventually passes through a narrow structure in the ankle (the tarsal tunnel). When there is an obstruction within or outside the tunnel that causes the tibial nerve to become pressurized or compressed, this is known as tarsal tunnel syndrome. The symptoms of tarsal tunnel syndrome may occur anywhere along the path of the tibial nerve, including the inside of the ankle and on the bottom of the foot. Symptoms may include tingling or numbness, shooting, sharp pains, burning, pins-and-needles sensations, or electric shocks. Any number of factors may cause the tibial nerve to become pinched, from benign growths within or outside the tarsal tunnel, inflammation from injuries or arthritis, diabetes, flat feet, and more. A podiatrist may treat tarsal tunnel syndrome with anti-inflammatory medications, steroid injections, custom shoes, orthotics, or even surgery in severe cases. It is important to seek treatment from a podiatrist for tarsal tunnel syndrome as failure to repair the nerve may result in permanent nerve damage.

Tarsal tunnel syndrome can be very uncomfortable to live with. If you are experiencing tarsal tunnel syndrome, contact Kellvan Cheng, DPM of Elite Foot & Ankle. Our doctor can provide the care you need to keep you pain-free and on your feet.

Tarsal Tunnel Syndrome

Tarsal tunnel syndrome, which can also be called tibial nerve dysfunction, is an uncommon condition of misfiring peripheral nerves in the foot. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome, the tibial nerve is damaged, causing problems with movement and feeling in the foot of the affected leg.

Common Cause of Tarsal Tunnel Syndrome

• Involves pressure or an injury, direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or near the knee.
• Diseases that damage nerves, including diabetes, may cause tarsal tunnel syndrome.
• At times, tarsal tunnel syndrome can appear without an obvious cause in some cases.

The Effects of Tarsal Tunnel Syndrome

• Different sensations, an afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg.
• The foot muscles, toes and ankle become weaker, and curling your toes or flexing your foot can become difficult.
• If condition worsens, infections and ulcers may develop on the foot that is experiencing the syndrome.

A physical exam of the leg can help identify the presence of tarsal tunnel syndrome. Medical tests, such as a nerve biopsy, are also used to diagnose the condition. Patients may receive physical therapy and prescriptive medication. In extreme cases, some may require surgery.
